On this page is an exponent calculator. Enter a base b and an exponent or power n, and we'll compute the result of exponentiation.

What is an exponent?
An exponent is a power or a symbol in mathematics which is shorthand to multiply a number by itself n times. Exponentiation means to find the result of raising a base to some exponent or power n.
Exponentiation is the opposite of taking a logarithm. Where in exponentiation we know the base and the power, in a logarithm we know the result and the base. In that way, we can convert back and forth between the two.
Exponent formula
The formula for an exponent is:
Where:
- b: the base of the equation (the number we need to raise/take a power/exponentiate)
- n: the power or exponent
If the power is a fraction it's a bit trickier. See our dedicated fraction exponent calculator for more.
Exponent example
For example, let's say you wanted to find 5^5. Here's how it'd work:
5 raised to the fifth power is 3,125.
Using the exponent calculator
Enter two numbers to get the result of exponentiation: the base b and the power or exponent n. The calculator updates in real time as you type.
Quick buttons set common values: e (Euler's number), bases 10 and 2, and exponents for squaring, cubing, square roots, and inverses. Type e in the base field to use Euler's number (~2.718). The Special Cases section shows your base raised to six common powers.
